Hey Bob, just ran across a futon mattress that a friend of mine is willing to let go of cheap. I believe it's either a single or twin, will confirm that, but I saw it and he has it wrapped in the original plastic. Evidently he bought it to use for guests when they visited - not often. So, it looks great. Either the fabric covering it is dark Navy blue, or it has some sort of slip cover. I'm headed over to his house tomarrow and will check these things out and get back with you.
